The Hydraforce PC08-30-0-V-XXX (5220001) is a pilot-operated hydraulic check valve designed for use in blocking or load-holding circuits. This screw-in, cartridge-style valve allows free flow from port 2 to port 3 and normally blocks flow from port 3 to port 2. Flow is permitted from port 3 to port 2 when pressure is applied at port 1, making it suitable for various hydraulic applications where controlled flow direction is necessary. The valve features a hardened seat that ensures long life and minimal leakage, enhancing system reliability. It offers optional configurations including a sealed piston and various spring ranges, allowing customization to meet specific application requirements. Its compact size facilitates easy integration into tight spaces within hydraulic systems. This model operates effectively within a pressure rating of up to 3500 psi (241 bar) and has specific flow ratings that can be referenced from its performance chart. The maximum internal leakage rates are impressively low, with different rates specified between various ports, ensuring efficient operation. It supports a broad range of operating fluid temperatures which varies with the seal material used—ranging from -40°C to +100°C for Buna N seals and up to +204°C for Viton seals. Additionally, the PC08-30-0-V-XXX is compatible with mineral-based or synthetic hydraulic fluids with lubricating properties, accommodating fluid viscosities from 7.4 to 420 cSt. The unit's robust design adheres to ISO 4406 contamination level standards, ensuring durability and consistent performance in challenging environments. For installation, this valve fits into an 08-size-3-way cavity (VC083) and does not have orientation restrictions during installation. Various seal kits such as Buna N, Viton, Polyurethane, and Urethane are available for this model, along with corresponding installation instructions.
